A brain stroke is the same as a heart attack, which occurs when there is a problem with blood flow to a part of your brain.

Stroke is a life-threatening emergency and immediate medical care is critical to avoid permanent damage and death.
What is Stroke?
A stroke happens when blood flow to the brain is blocked. This prevents the brain from getting oxygen from the blood. Without oxygen and nutrients, brain cells begin to die within minutes. Sudden bleeding in the brain can also cause a stroke if it damages brain cells. A stroke is a medical emergency. It can cause lasting brain damage, long-term disability, even death.
Stroke results from a sudden disruption of the blood flow to the brain and there are two major types of strokes, Ischemic stroke and Hemorrhagic stroke.
Human brain is a very needy organ and that`s why it requires a high blood volume. When the flow is disrupted like, for example in a case of a tiny blood clot travelling to the brain vessel and occluding it brain cells begin to die. This can happen within minutes from the blood flow disruption and that`s why stroke is an emergency.
